A manufacturer of hair care products tested a new shampoo on 5,000 people, and 0.3 percent of the participants experienced a moderate allergic response. 15 of the 5,000 individuals experienced a minor allergic response.
<h3>Define percentage.</h3>
The easiest approach to utilizing percentages is to compare two numbers while setting the second amount's base to 100. Consider for a moment that we are interested in the proportion of working women. A percentage (%) is a number that represents how many out of 100 it is and may also be written as a decimal or fraction. To convert a percentage to a fraction, place the percentage's value in the numerator and 100 in the denominator.
Given,
15 of the 5,000 individuals experienced a minor allergic response.
Dividing the percentage of the population that had a minor reaction.
15 ÷ 5000
0.003
Multiplying it by 100 for percentage:
0.003 × 100%
0.3%
0.3% percent of the people had mild allergic reactions.

Answer: $7800 was invested at 9%
$5900 was invested at 3%
Step-by-step explanation:
Let x represent the amount invested in the fund that paid a dividend of 9%.
Let y represent the amount invested in the fund that paid a dividend of 3%.
Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $879. This means that
0.09x + 0.03y = 879- - - - - - - - - 1
This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $839. It means that
0.1x + 0.01y = 839 - - - - - - - - - -2
Multiplying equation 1 by 0.1 and equation 2 by 0.09, it becomes
0.009x + 0.003y = 87.9
0.009x + 0.0009y = 75.51
Subtracting, it becomes
0.0021y = 12.39
y = 12.39/0.0021
y = 5900
Substituting y = 5900 into equation 1, it becomes
0.09x + 0.03 × 5900 = 879
0.09x + 177 = 879
0.09x = 879 - 177
0.09x = 702
x = 702/0.09
x = 7800

Answer:
$ 2100
Step-by-step explanation:
De la pregunta anterior:
1 metro de cerca de alambre = $ 150
14 metros = x
Cruz multiplicar
x = 14 × $ 150
x = $ 2100
Por lo tanto, costaría $ 2100 por una cerca de 14 metros
